Antiepileptic Drugs: GABAergic Pathway Potentiators01:18

Antiepileptic Drugs: GABAergic Pathway Potentiators

425
γ-aminobutyric acid or GABA, plays a pivotal role as an inhibitory neurotransmitter in the brain. GABA pathway potentiators, also known as GABAergic drugs, are a class of pharmaceutical agents designed to enhance the functioning of the GABAergic system. These medications primarily treat epilepsy, a neurological disorder characterized by recurrent seizures.
The key GABA pathway potentiators used in epilepsy management are as follows.
Benzodiazepines are a well-known class of drugs used for...

Arteries of the Lower Limbs

194
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Antiepileptic Drugs: Calcium Channel Blockers01:17

Antiepileptic Drugs: Calcium Channel Blockers

418
Calcium channel blockers, a class of antiepileptic drugs, regulate the flow of calcium ions within neurons.
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein01:20

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

318
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Antiepileptic Drugs: Glutamate Antagonists01:14

Antiepileptic Drugs: Glutamate Antagonists

383
Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...

Antiepileptic Drugs: Potassium Channel Activators01:20

Antiepileptic Drugs: Potassium Channel Activators

192
Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.
Ezogabine has gained approval as an adjunctive treatment...

Area of Science:

  • Neurology
  • Neuroscience
  • Pharmacology

Background:

  • Epilepsy is a common neurological disorder characterized by recurrent seizures.
  • Its underlying mechanisms, including blood-brain barrier disruption, neuroinflammation, and apoptosis, are not fully understood.
  • Activated Protein C (APC) targets these pathological pathways.

Purpose of the Study:

  • To review the mechanisms of epilepsy.
  • To explore the functions and neuroprotective properties of Activated Protein C (APC).
  • To investigate the potential association between APC and epilepsy pathogenesis.

Main Methods:

  • Literature review of epilepsy mechanisms.
  • Analysis of APC's anti-inflammatory and anti-apoptotic functions.
  • Evaluation of APC's effects on blood-brain barrier, endothelial cells, and gene expression.

Main Results:

  • APC exhibits anti-inflammatory effects by downregulating thrombin.
  • APC acts as an anti-apoptotic protein, inhibiting p53-mediated apoptosis.
  • APC demonstrates neuroprotective effects by preserving blood-brain barrier integrity and downregulating pro-inflammatory/pro-apoptotic genes.

Conclusions:

  • APC's multifaceted actions on neuroinflammation, apoptosis, and blood-brain barrier dysfunction suggest therapeutic potential for epilepsy.
  • APC may prevent or reduce the severity of epilepsy through its neuroprotective and neurogenic properties.
  • Further research into APC's role in epilepsy is warranted.
